"Began taking the 37.5 mg version on 2/23/14 and I've lost 7.8 pounds in 6 days--tomorrow will be one week.  I've gone to the gym 5 of the 6 days for 50 minutes of elliptical workout.  I've been eating just under 500 calories a day, and I have to make myself eat because food doesn't seem appealing at all--it's the weirdest thing.  I take my pill at 11 am and have no trouble falling asleep around 10:15 pm.  Will post again next week with more details.  I'm 5'7 (and 1/2) and started my diet at 191.6 pounds."
